This would cause abrupt loss of rainfall, atmospheric change and climate change. Widespread starvation combined with lack of decomposition would cause rampant disease.
What will humans look like in 100 000 years?
100,000 Years From Today We will also have larger nostrils, to make breathing easier in new environments that may not be on earth. Denser hair helps to prevent heat loss from their even larger heads. Our ability to control human biology means that the man and woman of the future will have perfectly symmetrical faces.
Can humans survive without animals?
Animals provide many beneficial things to humans and without them, even with plants, humans would eventually go extinct because the ecosystem just lost a huge chunk.
